Conventional smoothing over complicated coastal and island regions may result in errors across boundaries, due to the use of Euclidean distances to measure interpoint similarity. The new Complex Region Spatial Smoother (CReSS) method presented here uses estimated geodesic distances, model averaging, and a local radial basis function to provide improved smoothing over complex domains. CReSS is compared, via simulation, with recent related smoothing techniques, Thin Plate Splines (TPS), geodesic low rank TPS (GLTPS), and the Soap film smoother (SOAP). The GLTPS method cannot be used in areas with islands and SOAP can be hard to parameterize. CReSS is comparable with, if not better than, all considered methods on a range of simulations. Supplementary materials for this article are available online.

• Spatial models for distance sampling data: recent developments and future directions (2013, background): “Previous work (Ramsay 2002; Wang & Ranalli 2007; Wood et al. 2008; Scott-Hayward et al. 2013; Miller 2012) has highlighted the need to take care when smoothing over areas with complicated boundaries, for example, those with rivers, peninsulae or islands.”
